Ah - that is expected behaviour because you are using the specialised vector-only operators in "mikera.vectorz.core". These are fast type-hinted versions of functions (that only work on vectors).
If you want to use the broadcasting operations that work with different types, you need to use the operators in "clojure.core.matrix.operators". In general, it is usually better to use the core.matrix API as it provides more capabilities and flexibility. It would be nice if one version could do everything, however currently Clojure doesn't allow overloading functions on type, so we need to have the different namespaces.
